... the fretting wear between deformable crossed parabolic cylinders. Fretting is achieved by the application of a periodic displacement-controlled load, while the contact pair is defined as the same material, i.e., carbon steel/carbon steel, copper alloy/copper alloy, and aluminum alloy/aluminum alloy. Meanwhile...

... of fretting wear and corrosion. Thus, to investigate the synergistic damage mechanism, a flow-induced vibration wear simulated method was used to investigate the flow-induced vibration wear behavior of 690 alloy tube against 304 SS plate at 100 °C, 200 °C, and 285 °C in steam/water environment. Results show...

...Arman Ahmadi; Farshid Sadeghi In this investigation, a three-dimensional (3D) finite element model (FEM) was developed to study fretting wear of Hertzian circular and line contacts. The wear law incorporated in this model is based on the accumulated dissipated energy (ADE). A stress-based damage...
